Prognostic value of low-dose dobutamine echocardiography in patients with idiopathic dilated cardiomyopathy.
STUDY OBJECTIVES Dobutamine echocardiography is widely used for the evaluation of myocardial contractile reserve. The purpose of the study was to determine the prognostic value of low-dose dobutamine echocardiography in patients with idiopathic dilated cardiomyopathy (IDCM). PATIENTS The study group consisted of 77 consecutive patients with recently diagnosed IDCM (mean [+/- SD] age, 49 +/- 9...

OBJECTIVES The purpose of this study was to determine, by analyzing the pressure-volume relationship, the prognostic value of parameters related to myocardial energetics for predicting mortality in patients with dilated cardiomyopathy (DCM) in sinus rhythm. BACKGROUND The relationship between the myocardial energetics and the prognosis of patients with DCM in sinus rhythm remains unclear. M...
متن کاملRight ventricular dysfunction in patients with idiopathic dilated cardiomyopathy: Prognostic value and predictive factors.
BACKGROUND Right ventricular (RV) dysfunction is an important predictor of impaired prognosis in idiopathic dilated cardiomyopathy. AIMS To determine the prognostic role of RV dysfunction, independent of left ventricular (LV) dysfunction. METHODS A total of 136 consecutive patients (73% men; mean age 59.0±13.2 years) with idiopathic dilated cardiomyopathy (LV ejection fraction ≤ 45%) were e...
